Since updating 2.0.1 to 2.1.1 I get the following error “ Config flow could not be loaded: 500 Internal Server Error Server got itself in trouble” even removing the component and installing 2.1.1 I get the same error when try to configure the component (where I would try and enter the URL).
I also tried ver 2.1 but that also has the same issue, rolling back 2.0.1 worked. My version of HA is 26.1.1
